HOW TO CONSTRUCT TWO PARALLEL LINES GEOMETRICALLY BY USING MY COMPASS?
Here is the answer to your query.
To construct parallel lines using compass steps of construction are as follows
Step I : Draw a ray AB.
Step II : With centre A any radius draw on arc cutting AB at C.
Step III : With centre C and same radius draw an arc cutting the previous arc at D.
Step IV : Join AD and produce it to point E.
Step V : Now with centre E and any radius draw an arc cutting AE at F.
Step VI : With centre F and same radius draw an arc cutting the previous arc at G.
Step VII : Join EG and produce it to obtain ray EH.
Now EH || AB because ∠EAB = ∠AEH = 60° (Alternate Opposite angles)
